What is the difference between a module and a device?
Module: A technological module includes the mechanics, the electronics and the control hardware as well as the associated control program. Device: Device designates the control hardware, e.g. PLC or distributed peripheral (I/O).
What does a kernel module do?
Kernel modules are pieces of code that can be loaded and unloaded into the kernel upon demand. They extend the functionality of the kernel without the need to reboot the system. It is easier to diagnose system problems. A bug in a device driver which is bound into the kernel can stop the system from booting at all.
What is a device module?
The Device module extends Highstage into the operational phase of the life of a product. It can be used to manage all your shipped devices, or to communicate with your installed devices. It can also be used internally to manage the operational history of devices, or e.g. the customer complaint processes.
What’s the difference between a device driver and a kernel?
From my understanding, the device driver is a computer program that handles specific hardware components. I also know that the kernel is a computer program that acts as a bridge from software to hardware. For some reason, my mind can’t differentiate the two. When it comes to the windows platform, can somebody explain the difference to me…
What’s the difference between a module and a device?
Device files like /dev/tty or /dev/null exist so your program can interface with a driver. A module is a piece of a kernel that can be optionally loaded into the kernel. This is from the perspective of the kernel. CUPS talks about “drivers” while Perl talks about modules.
Which is the kernel driver for the NVIDIA GPU?
A kernel driver is a program (kernel module) that is designed to drive a piece of hardware. The lspci output says nvidia is the kernel driver as it is the loaded module for the device. Along with it comes other available kernel modules available. I’ll add that the commands in linux to list and remove drivers are lsmod and rmmod respectively.
Why do you not need dynamic kernel drivers?
That is to say, if you know in advance exactly which drivers will always be needed and that this will never change, you have a good reason not to bother with dynamic kernel modules. If you build your kernel statically and disable Linux’s dynamic module loading feature, you prevent run-time modification of the kernel code.
